Abstract

Die Erfindung betrifft eine Schnittstellenschaltung, die sich zum Betrieb von kapazitiven Lasten wie elektrische Vorschaltgeräte für Lampen an einer Netzversorgungsschaltung, insbesondere einem Phasenanschnittsdimmer, eignet. Die erfindungsgemäße Schnittstellenschaltung schließt den Lasteingang kurz, wenn die Netzversorgungsschaltung keine Lastversorgung durchführt.

Figure 00000001
The invention relates to an interface circuit, which is suitable for the operation of capacitive loads such as electrical ballasts for lamps on a power supply circuit, in particular a Phasenanschnittsimmer. The interface circuit according to the invention short-circuits the load input when the power supply circuit does not perform any load supply.
